To al?. whom it may concern,.-

Be it known that I, Monms B. BREWs'rER, a citizen of the United States, residing at Columbus, in the county of Franklin and State ol" Ohio, have invented certain new andnseful Improvements in Elevators and Convey ers, of which the following is aspecification.

My invention relates to a new and useful improvement in elevators and conveyers, and more particularly to those designed for elevating and conveying fuel from a tender to the hopper of a mechanical Stoker located on a locomotive.

The object of the invention is to rovide means located at the forward end of t e tender for elevating fuel up either side thereof and then conveying the :same centrally overhead to the hopper of the Stoker carried on' the locomotive. By such an arrangement the platforms of the' locomotive and the tender are unobstructedl and'free access is hadv to the ire-doors and the tender.

Another feature resides in a grate havinga.

plurality of openings of such dimensions as to allow only the-propersized lumps of coal to pass through. By the term propersized lumps of'coa ASuch sized lumps as will readily be acted upon by the elevator and conveyer and properly combusted when delivered to the {ire-box are referred to.

Finally, the object of the invention is to provide a device of the character described that will be strong, durable, efficient, simple, and comparatively inexpensive to build and one in which the severalparts Will not fbe liable to get out of working order.

With the above and other objectsnin view the invention relates to the novel details of construction andoperation, a referable embodiment of which isdescribe in the specification, and illustrated in the accompanying drawings, wherein- Figure 1 is a view showing a portion of the forward end of a tender in vertical section and my elevator arranged thereon in vertical section and the conveyer projecting therefrom in elevation, a portion of a locomotive and an automatic Stoker being also illustrated in their relative positions to the conveyor and elevator. Fig. 2 is a vertical transverse sectional view taken on the line a: :u of Fig. 4 and looking from the rear of the tender and showing the Stoker in elevation .d the outline of the boiler partl in full lines andA partly in dotted lines. iig. 3 is o. partial longitudinal sectional view through the grate and its adjacent parts on the line -y y of Fig. 2. Fig. 4 is a plan view of the various parts in their relative positions, the elevator-casing being broken away Aon top to show the construction lying beneath; and Fig. 5 is a plan view of the grate.

In the drawings the numeral l designates the forward portion of ordinary locomotive-tender, upon each sidel of which are arranged the usual water-tanks 2, disposed so as to form,` the ordinary fuel `inner space 3. At the bottom of the inner s ace 3 is arranged a downwardly and forwardly inclined plate or looring', which serves to iced the fuel forward to a grate 5. The grate 5 is suitably mounted in an a Gle-iron frame 6, as shown in Fig. 3, su porte in the forward end of the plate 4 an the rear portion of .the usual platform 7 of the tender. The grate, as shown in Fig. 5, is provided with aplurality :of rectangular openings 8 of such dimensions as to allow only the pro er-sized lumps of coal or fuel 'to fall throng 1, and the grate is constructed so asy to withstand considerable strain as would be occasioned by the crushing of the fuel thereon to break the saine into the proper-sized lum s to pass through the openings 8. Exten ing beneath and upwardly from the ends or' the grate and be-- tween the water-'tanks 2 is a substantially rectangular vertical elevatingcasing 9, suit ably constructed, preferably' of sheet metal, and having arranged at each corner transverse lower shafts 10 and upper shafts 1 1 and 12. The inner walls of the casing are bulged inward adjacent the shafts, as indicated at 13, to acconnnodate s rockets 14, arranged in pairs, tivo upon eac of the Shafts, and at the sides of the casing.l Sprocket conveyerchains 1-5 are mounted upon the sprockets 14 at each side of the casing, 'as indicated in Buckets 16 are fixe' y sup orted between the chains und are lrefera ly V-shaped in cross sectir in, so as to readily and effec-tuali y scoop up the fuel and dump the same. Of course it is to be understood th at the casing 9 is cutaway beneath the grate, so as to allow the fuel to drop .thereinto The casing hencath the grate is formed at its front and rear sides with outwardly and upwardl inclined portions 17, so as to direct the fue falling through the openings 8 into the casing 9i.l

Arranged on each side of the casing an the bottom of the inclined portion 17 are angle-irons 18, acting as guide-shoes, beneath The lower guide-slices also prevent sagging,

and their extended portions serve to support the chains and the buckets until they have rounded the sprocket-wheel 14 and started on their vertical flight. Facing-plates ex-v tend downwardly from the shoes to the bot` tom and outer wall of the casing, thus preventing the fuel `from getting beneath the; said shoes. i

The sprocket-chains 15 and the buckets,

with reference to Fig. 2, travel upward on the' right-hand side 'and downward on the left-hand side, the buckets on the right-hand side being carried right side -up and loaded and the buckets on the left-hand side being inverted and unloaded. As the buckets are carried around the lower left-hand sprocketl 14 they are brought to a vertical position, as indicated in theV said Fig. 2,'iso as to scoop up the` fuel which falls throu hgthe openings 8 of the grate 5 as the said uckets passthereunder, and as they .pass around the lower righthand sprocket14 they are again broughtA to a horizontal position ri ht side .up and loaded, in which position they remainuntil they ass over the upper right-hand sprocket 14, wnen they will again be brought to a vertical position and dump the fueLas will be apparent from the said figure. For imparting motion to the chains 15 I preferably extend the shaft 11, sol that the same may be suitably connected with a source of ower to` transmit motion to the sprocketwvlieels 14, carried on the said shaft. Motion thus being im arted to the said s rockets, the chains 15` wi l be driven, while t e other sprockets willl operate merely as idlers, the shaft l1 acting to further transmit motion, as will be 'hereinafter described. The shaft 12v is suitably slidably mounted, so that the slack in the.

rocket-chains 15 may be taken u while tightening-sprockets 21 are dispos within the casing slightly below the upper left/handsprockets 14 as shown in Fig. 2, and engage with the said sprocketchains 15.

Extending forwardly and from the central upper port-ion of the casing` 9 is a conve ertrough 22, arranged beneath the inner w lof the said casing, hich is formed with an opening 23, so as to allow the fuel to drop into the said trough. The trough is closed at its rear end by the rear wall of the casin and rests in ahanger 25, havingits free en s bent down and suitably fastened upon the top of the casing-9'.-` Arranged within the trough is an ordinary screw conveyer 26, whose shaft'27 .is mounted at its forward end in a boxing 28,

supported between the ends of the side flanges 29 ofthe trough 23, which side flanges 'iroject a short distance beyond'the saidl troug conse quently causing the extreme outer end of the convcyer to project out of and beyond the trough, so as to carry the fuel therefrom. The trough and the exposed portion of the conveyor 26 are Vdis osed directl f over the hopper 30 of a suitab e mechanical stolzer 31.

The rear end of the shaft 27 rejects through -and beyond the rear vertica wall of the cas ing from which it is supported and has keyed u on its projecting portion a sprocket 32, w )ich is connected, b means of a sprocketchain 33, with a sprocket 34, keyed upon the shaft-11. As before described, motion being imparted to the shaft 11 by the sprockets 14,4 it 1s ap arent that thesaid sprocket 34 will be revo vcd andniotion transmitted from the sprocket 'by means of the chain 33 to the s rocket 32, which latter being fined upon t e shaft ,27' of the conveyer will revolve the same and cause the fuel dumped from the bucket 17 through the opening 234 into the trough 22 to be conve ed forward to the end of the trough, from w ich point it will drop into the hopper 30.

By carryiu the fuel up the side ot the inner space 3 t e same is left free and unobpass into the tender. and that he may also use the longhandled pokers and im lements without interference on the part o the elevator, and by disposing thev conveyer centra-lly overhead the fireman is afforded free access t0 the {irc-doors, which are indicated in Fig. 1 of the drawings by the numeral 36, so that he may stoke the furnace by hand should he desire or 1n case of accident to the Stoker 'or the elevator and conveyer.

Another material advantage gained by 'arranging and constructing the parts as herein described is the removing of all fuel-delivering mechanism from and about thesidcs and lower portion of the boiler and also obviating the detrimental 'efects of the lost motion be tween the tender and the locomotive. Fun ther, it Vwill be observed thatthe conve yer. being disposed centrally over the hopper 30 the roundin of Shar curv( s and the swaying of the ten er and lbcomcnive will not'in any way interfere with the cgntiuuous delivery of the fuel to the ho per. y

ln conclusion Ipwish itundcrsiood that the essentialfeature of the invention is the construction and arrangeme ut of the parts so as to elevateftheufuel from the bottoni of the tenderup its side to a central overhead con veyer and to convey the 'fuel centrailv over-- head above the platform. et the tender and deck ofthe locomotive to the hopper elf the Stoker, and in View of this fact various struCted, so that the fireman may readily IOC . end of Said means lying in juxtaposition to ymotive-tender2 of means for conveyin fuel changes may be made in the construction and operation wholly within the sco e of the claims and without departing from t e Spirit of my, invention.

Having'now fully described my inventidn, what I claim, and desire to secure `by Letters Patent, is

1. The combination with a locomotivcfa Stoker for Supplying fuel thereto and a locofrom the tender to the Stoker, the de ivery the Stoker, but movable laterally with relation thereto.

2. The combination with a locomotive, a Stoker for supplying fuel thereto and a locomotive-tender, of means for conveying fuel from the tender to the Stoker, Said means be-y ing mounted upon the tender centrally thereof and extending longitudinally overhead from the tender toward the locomotive with its delivery end in juxtaposition to the Stoker and movable laterallywith relation thereto.

3. Means for feeding fuel from a locomotive-tender to the hopper of a mechanical Stoker carried on the locomotive, comprisirlr a device for elevating thefuel up the side oli the tender, and means for conveying the fuel overhead from the said device to the hopper 4. 'In av device of the character described, the combination with a Stoker and a locomotive-tender, of means for elevating fuel up one Side of the tender and partly across the Same overhead, and a conveyor associat :d with the elevator and extending overhead therefrom to convey the fuel from the elevate, ing means to the Stoker;

5. The combination with a locomotivetender and a Stoker, of a grate located in the tender, means for elevating fuel from be- Death the grate up one side of the tender, and a conveyer for conveying the fuel from the elevating means to the Stoker.
